[0035] As shown in the background, in the prior art, the signal coverage in the elevator can be achieved by installing an omnidirectional antenna on each floor of the building, and then relying on the electromagnetic waves entering the elevator car through the omnidirectional antenna to communicate. It should be noted that the omnidirectional antenna exhibits 360-degree uniform radiation in the horizontal direction, that is, the so-called non-directionality, so that the omnidirectional antenna can emit signals in all directions.

[0036] However, the above-mentioned electromagnetic wave power entering the elevator car is limited, resulting in poor signal coverage effect of the elevator car.

[0037] Based on this, the elevator provided by the application comprises an elevator car, a signal source, a gain antenna and a first antenna. The signal source is used for connecting an external communication network. The gain antenna is arranged on the inner top of the elevator shaft and is electrically connected with the signal source to receive signals from the signal source and transmit the signals to the elevator shaft after amplification. The first antenna is arranged on the outer top of the elevator car and receives the signals transmitted by the gain antenna, amplifies the signals and transmits the signals to the elevator car, so that the elevator car has sufficient signal strength, thereby improving the signal coverage effect of the elevator car.

[0038] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described below in greater detail with reference to the drawings in the preferred embodiments of the present application. Identical or similar reference numerals are used to represent identical or similar components or components having identical or similar functions throughout the drawings. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation on the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0039] Referring to Figure 1 The elevator provided by the application comprises an elevator car 100, a signal source 200, a gain antenna 300 and a first antenna 400. The signal source 200 is used for connecting an external communication network.

[0040] The gain antenna 300 is arranged on the inner top of the elevator shaft 10 and is electrically connected with the signal source 200.

[0041] The first antenna 400 is arranged on the outer top of the elevator car 100 and receives the signals transmitted by the gain antenna 300, amplifies the signals and transmits the signals to the elevator car 100.

[0042] It can be understood that the elevator shaft 10 is a vertical passage for the operation of the elevator car 100 and is generally built of concrete or steel structure and penetrates through multiple floors of a building. The elevator shaft 10 provides a safe and controlled operating environment for the elevator car 100 and should have sufficient width and depth to accommodate the elevator car 100 and its supporting equipment such as guide rails, counterweights and cables. The elevator car 100 is a closed space for carrying passengers or goods and provides a safe and comfortable transportation environment. The elevator car 100 moves vertically in the elevator shaft 10 to transport passengers or goods from one floor to another.

[0043] It should be noted that the signal source 200 is the signal provider for the elevator. The signal source 200 can be connected to an external communication network (such as a mobile communication network) via an antenna to introduce external signals into the elevator. In a specific implementation, an elevator machine room 20 can be set above the elevator shaft 10, close to the gain antenna 300. The signal source 200 is set inside the elevator machine room 20 to facilitate the connection between the signal source 200 and the gain antenna 300, reduce signal loss along the transmission path, and improve signal transmission efficiency.

[0044] The gain antenna 300 is used to receive signals from the signal source 200, amplify them, and transmit them downwards into the elevator shaft 10. The high gain characteristic of the gain antenna 300 helps to improve signal strength and coverage. The gain antenna 300 is installed at the inner top of the elevator shaft 10 so as to cover the entire elevator shaft 10.

[0045] The first antenna 400 is installed on the outer top of the elevator car 100. It is responsible for receiving signals from the gain antenna 300, amplifying the signals, and transmitting them into the elevator car 100 (or to communication equipment inside the elevator car 100). The first antenna 400 can act as a signal relay and amplifier to ensure sufficient signal strength inside the elevator car 100. The first antenna 400 should be securely installed on the top of the elevator car 100. Exemplarily, the first antenna 400 can be fixed to the top of the elevator car 100 using a mounting bracket, or it can be fixed in other ways. This application embodiment does not impose too many restrictions on this. It should be noted that the first antenna 400 is a passive device and does not require power supply, avoiding the risk of electrical connection and reducing construction costs.

[0046] Understandably, compared to the poor signal coverage of elevators in existing technologies, the elevator provided in this application embodiment improves signal coverage by incorporating an elevator car 100, a signal source 200, a gain antenna 300, and a first antenna 400. The signal source 200 connects to an external communication network. The gain antenna 300 is positioned at the inner top of the elevator shaft 10 and is electrically connected to the signal source 200 to receive signals from the signal source 200, amplify them, and transmit them downwards into the elevator shaft 10. The first antenna 400 is positioned at the outer top of the elevator car 100. The first antenna 400 receives signals from the gain antenna 300, amplifies them, and transmits them into the elevator car 100, ensuring sufficient signal strength within the elevator car 100 and thus improving the signal coverage of the elevator car 100.

[0047] In some embodiments, refer to Figure 1 As shown, the first antenna 400 is a lens antenna.

[0048] It should be noted that a lens antenna is an antenna that uses an electromagnetic lens to focus or expand radio waves. The lens antenna controls the direction and shape of the beam by changing the propagation path of the electromagnetic waves, similar to the effect of an optical lens on light waves.

[0049] A lens antenna can effectively focus electromagnetic waves, enabling it to transmit or receive stronger signals in a specific direction. This results in more uniform signal coverage within the elevator car 100, improving communication quality within the elevator. The lens antenna, positioned at the top of the elevator car 100, can achieve signal gain, enhancing signal strength within the elevator car 100.

[0050] In some embodiments, refer to Figure 1 As shown, the projection of the gain antenna 300 along the height direction of the elevator shaft 10 is located on the first antenna 400.

[0051] Specifically, the projection of the gain antenna 300 coincides with that of the first antenna 400, so that the first antenna 400 can better receive the signal emitted by the gain antenna 300, further ensuring the signal coverage effect of the elevator car 100.

[0052] The projection of the gain antenna 300 along the height direction of the elevator shaft 10 is located on the first antenna 400, which can also reduce signal loss during propagation and improve transmission efficiency.

[0053] In some embodiments, refer to Figure 1 As shown, the elevator also includes at least one second antenna 500, which is installed on the side wall of the elevator shaft 10 and is used to reflect the signal emitted by the gain antenna 300 to the elevator car 100.

[0054] It should be noted that by installing a second antenna 500 on the side wall of the elevator shaft 10, when the elevator car 100 is far from the gain antenna 300, the second antenna 500 can effectively reflect the signal emitted by the gain antenna 300 back to the elevator car 100, further enhancing the signal coverage within the elevator car 100. Exemplarily, the second antenna 500 can be a lens antenna or other passive antennas with reflective effects; this application embodiment does not impose excessive limitations on this.

[0055] Understandably, the second antenna 500 can direct the signal to the elevator car 100, thereby improving the signal strength and quality and enhancing the communication experience within the elevator car 100.

[0056] In some embodiments, refer to Figure 1 As shown, the second line 500 is set in the vertical direction.

[0057] Specifically, the vertical setting of the second antenna 500 can better cover the entire vertical movement range of the elevator car 100 in the shaft, ensuring that the signal can be effectively reflected and covered no matter which floor the elevator car 100 is on.

[0058] It should be noted that setting up a second antenna 500 in the vertical direction can also provide a consistent signal strength for the elevator car 100 during its up-and-down movement, reducing signal fluctuations.

[0059] In some embodiments, refer to Figure 1 As shown, there are at least two second-level antennas 500, and each second-level antenna 500 is located on the same side of the elevator car 100.

[0060] Understandably, by setting up multiple second antennas 500, the signal reception and reflection capabilities can be increased, further improving the signal strength inside the elevator car 100 and enhancing communication quality.

[0061] It should be noted that each of the second antennas 500 is positioned on the same side of the elevator car 100. The second antennas 500 can work collaboratively to more effectively reflect the signal emitted by the gain antenna 300 onto the elevator car 100, enhancing signal strength and coverage. Concentrating the second antennas 500 on one side allows for better control of the signal reflection path, reducing unnecessary scattering and loss, thereby improving signal transmission efficiency and quality.

[0062] In some embodiments, refer to Figure 1 As shown, the elevator also includes a third antenna 600, which is disposed between the gain antenna 300 and the elevator car 100. The third antenna 600 is used to transmit the signal emitted by the gain antenna 300 to the elevator car 100.

[0063] Understandably, the third antenna 600 can effectively project the signal emitted by the gain antenna 300 onto the elevator car 100, thereby reducing signal loss during transmission and improving signal transmission efficiency. Exemplarily, the third antenna 600 can be a lens antenna or other passive antennas; this embodiment does not impose excessive limitations on this.

[0064] It should be noted that by transmitting the signal, the third antenna 600 can help reduce signal scattering effects, thereby improving signal clarity and quality. The third antenna 600 can also be used to dynamically adjust the signal path and strength, reducing electromagnetic interference from external sources or other equipment within the shaft, ensuring signal stability.

[0065] In some embodiments, refer to Figure 1 As shown, the projection of the gain antenna 300 along the height direction of the elevator shaft 10 is located on the third antenna 600.

[0066] It should be noted that by aligning the projection of the gain antenna 300 with the third antenna 600, the third antenna 600 can better project the signals emitted by the gain antenna 300, reducing signal reflection and multipath effects on the walls of the elevator shaft 10, thereby improving signal quality and stability. It can also reduce signal loss during transmission, improve transmission efficiency, and ensure the reliability of communication within the elevator car 100.

[0067] In some embodiments, referring to Figure 1 As shown, the elevator further includes a feeder line 700, which electrically connects the signal source 200 with the gain antenna 300.

[0068] It should be noted that the feeder line 700 is a cable specially designed for transmitting radio frequency signals, with low loss characteristics. By using the feeder line 700, it can ensure that the signals emitted by the signal source 200 are transmitted to the gain antenna 300 with little loss, thereby improving the transmission efficiency of the signals.

[0069] It should also be noted that the feeder line 700 can effectively protect the signals from external electromagnetic interference, maintaining the integrity and quality of the signals. The feeder line 700 can be flexibly arranged within the elevator shaft 10, adapting to different building structures and elevator designs, and is easy to install and maintain.

[0070] In some embodiments, referring to Figure 1 As shown, the signal source 200 is one of a radio frequency remote unit and a repeater.

[0071] Specifically, the signal source 200 can be a radio frequency remote unit or a repeater, and the present application does not make too many limitations on this.

[0072] It should be noted that the radio frequency remote unit can provide strong signal output capability, enhancing signal coverage within the elevator shaft 10 and ensuring communication quality within the elevator. The radio frequency remote unit can support multi-band and multi-standard signal transmission, and can adapt to different communication needs and standards.

[0073] It should also be noted that the repeater can receive signals from the base station and amplify them before transmitting them into the elevator shaft 10, thereby enhancing signal strength and coverage. By amplifying and repeating the signals, the repeater can effectively reduce the signal blind area within the elevator shaft 10, ensuring the continuity of communication.

[0074] The skilled in the art can understand that the elevator provided by the application, by setting the elevator car 100, the signal source 200, the gain antenna 300 and the first antenna 400, the signal source 200 is used for connecting external communication network. The gain antenna 300 is arranged on the inner top of the elevator shaft 10, and the gain antenna 300 is electrically connected with the signal source 200 to receive the signal from the signal source 200 and transmit it downward to the inside of the elevator shaft 10 after amplification. The first antenna 400 is arranged on the outer top of the elevator car 100, the first antenna 400 receives the signal emitted by the gain antenna 300, amplifies it and transmits it to the inside of the elevator car 100, ensuring that the elevator car 100 has sufficient signal strength, thereby improving the signal coverage effect of the elevator car 100.

[0075] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example.

[0076] It can be understood that the various numerical numbers involved in the embodiments of the present application are only for the convenience of differentiation, and are not used to limit the scope of the embodiments of the present application.

[0077] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings, but the skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. The skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
